Hi man, thanks for script. But i have a small problem. Your code generate not valid bitcoin address. Not all time but sometimes. I modified your code and in the request I have 200 addresses. and periodically I get 500 response from the server. when I entered the list of addresses obtained by generating your code some addresses are not correct. can you help deal with this?

Where can i contact you for a custom made work?

Thank you very much for sharing your code, I really liked it and that is why I have taken the liberty to adapt it to python3.

Original:

pubkey2=hashlib.sha256(binascii.unhexlify('04'+pubkey)).hexdigest()
pubkey4=hashlib.sha256(binascii.unhexlify('00'+pubkey3)).hexdigest()

Final Code:

pubkey2=hashlib.sha256(binascii.unhexlify(b'04'+pubkey)).hexdigest()  # Encode as bytes
pubkey4=hashlib.sha256(binascii.unhexlify(b'00'+pubkey3.encode())).hexdigest()  # Encode '00' and pubkey3 as bytes

In the final version of the code, specific changes have been made to ensure that concatenation operations are carried out correctly. Here's the detailed explanation of the changes:

pubkey2 Encoding:

Originally, pubkey is a string of hexadecimal digits. To use it with the hashlib.sha256 function, you need to convert it into bytes. In the final version, a b is added before the string '04'+pubkey, indicating that it's bytes rather than a string.

pubkey4 Encoding:

Similarly, you need to convert '00'+pubkey3 into bytes before passing it to the hashlib.sha256 function. However, in this case, pubkey3 is a hexadecimal string, so you need to explicitly encode it using .encode(). Hence, b'00'+pubkey3.encode() is used.

Input String Encoding:

Also, in the main code block section, a line has been added to encode the input string (sys.argv[1]) into bytes using .encode('utf-8'). This is necessary to ensure that the input is handled properly in the hash operations. In the original version, the input was used directly, causing issues with hash operations in Python 3.

GET Request with urllib.request:

The part of the code that handles GET requests using urllib.request is well implemented and doesn't require any changes. This allows the script to retrieve information from blockchain.info.

These changes are made to ensure compatibility with Python 3 and to ensure that concatenation and manipulation of strings and bytes are done correctly.
